+# OpenSpec Change: enterprise-gaming-party
+
+- **Change ID**: enterprise-gaming-party
+- **Package**: `@suaveplan/party`
+- **Category**: gaming/multiplayer
+- **Target path**: `gaming/multiplayer/party`
+- **Status**: PROPOSED
+- **Date**: 2026-04-24
+- **Reference spec**: `/mnt/s/web/suaveplan/enterprise/party.md`
+
+---
+
+## Summary
+
+Deliver `@suaveplan/party` on the genesis branch from scratch at enterprise quality. The package provides a party/group system with invites, leadership transfer, and kick/promote mechanics. A `PartyManager` creates/destroys `Party` objects; a `Party` tracks members with role (leader/officer/member), handles invite expiry, and enforces `maxSize`. An `InviteTracker` manages pending invites with configurable TTL and accept/decline/expire lifecycle. Genesis adds Zod schemas, structured errors, OTel active-party gauge, injectable clock, and 100% coverage.
+

+
+## Current-state audit (genesis)
+
+Package does not exist on genesis yet — fresh build.
+
+---
+
+## Available workspace deps on genesis
+
+| Package | Role |
+|---|---|
+| `@suaveplan/error` (`workspace:^`) | `PartyError`; `PARTY.*` codes |
+| `@suaveplan/types` (`workspace:^`) | `Clock`, `IdGenerator` |
+| `@suaveplan/events` (`workspace:^`) | `party:invite`, `party:joined`, `party:left`, `party:disbanded` events |
+| `zod` (`catalog:forms`) | `PartyConfig`, `PartyMember` schemas |
+| `@opentelemetry/api` (`catalog:observability`) | Active party gauge |
+
+---
+
+## Public API surface
+
+```ts
+type PartyRole = 'leader' | 'officer' | 'member'
+
+interface PartyMember {
+  playerId: string
+  displayName: string
+  role: PartyRole
+  joinedAt: number
+}
+
+interface PartyConfig {
+  maxSize?: number        // default 5
+  inviteTtl?: number      // seconds, default 60
+}
+
+function createPartyManager(options?: { clock?: Clock }): PartyManager
+
+interface PartyManager {
+  createParty(leaderId: string, leaderName: string, config?: PartyConfig): Party
+  getParty(partyId: string): Party | undefined
+  getPartyByPlayer(playerId: string): Party | undefined
+  disbandParty(partyId: string): void
+  readonly count: number
+}
+
+interface Party {
+  readonly id: string
+  readonly members: ReadonlyMap<string, PartyMember>
+  readonly leaderId: string
+  readonly size: number
+  invite(fromId: string, toId: string, toName: string): string   // returns inviteId
+  acceptInvite(inviteId: string, playerId: string): void
+  declineInvite(inviteId: string): void
+  leave(playerId: string): void
+  kick(by: string, target: string): void
+  promote(by: string, target: string, role: 'officer' | 'leader'): void
+  tick(dt: number): void    // expire invites
+}
+```
+
+### Error codes
+
+```ts
+type PartyErrorCode =
+  | 'PARTY_NOT_FOUND'
+  | 'PARTY_FULL'
+  | 'PARTY_MEMBER_NOT_FOUND'
+  | 'PARTY_INVITE_NOT_FOUND'
+  | 'PARTY_INVITE_EXPIRED'
+  | 'PARTY_PERMISSION_DENIED'
+  | 'PARTY_ALREADY_IN_PARTY'
+```

+
+## Impact
+
+**Downstream**: `@suaveplan/react-social-game` shows party panel; `@suaveplan/lobby` transfers party to lobby. Prerequisites: `@suaveplan/error`, `@suaveplan/types`, `@suaveplan/events`.

+# Tasks: enterprise-gaming-party
+
+## 0. Pre-flight (non-negotiable)
+
+- [ ] 0.1 Confirm clean working tree (`git status` reports nothing) and no in-flight worktrees with uncommitted work (`git worktree list` then `git status` in each)
+- [ ] 0.2 If any worktrees exist under `.claude/worktrees/`, account for each one: still-active agent, work-pending-merge, or stale-and-prune. Stale worktrees MUST be removed (`git worktree remove`) before opening a new one — code that has been lost twice on main is the failure mode this guards against.
+- [ ] 0.3 Confirm the package set in `MANIFEST.md` matches `find packages -maxdepth 3 -name package.json` count. Drift here means a prior change archived without regenerating the manifest.
+
+## Phase 1 — Scaffold
+
+- [ ] Create `gaming/multiplayer/party/` (`@suaveplan/party`, `0.1.0`, `sideEffects: false`)
+- [ ] `tsconfig.json`, `vitest.config.ts`
+
+## Phase 2 — Error codes & constants
+
+- [ ] `src/error-codes.ts` + `src/constants/index.ts` — `DEFAULT_MAX_SIZE`, `DEFAULT_INVITE_TTL`
+
+## Phase 3 — Types
+
+- [ ] `src/types/common.ts` + `common.md`
+
+## Phase 4 — Party
+
+- [ ] `src/core/party/party.ts` — invite/accept/decline/leave/kick/promote, leader auto-transfer on leave, invite TTL tick
+- [ ] Tests (permission checks, invite expiry, leader re-election on leave)
+- [ ] Docs
+
+## Phase 5 — Party manager
+
+- [ ] `src/core/party-manager/party-manager.ts` — create/get/disband, player→party index, OTel gauge
+- [ ] Tests + docs
+
+## Phase 6 — Integration tests
+
+- [ ] `tests/integration.test.ts` — invite → accept → promote → leader leave → auto-reassign
+
+## Phase 7 — Pre-publish gate
+
+- [ ] `bunx turbo lint typecheck test --filter=@suaveplan/party` green
+- [ ] 100% coverage
+- [ ] Publish: `bun scripts/publish.ts --package @suaveplan/party`
